VALVE.

SPECIFICATION forming part of Letters Patent No. 755,334, dated March 22, 1904. Application filed September 24, 1903. Serial No. 174,409. (IT model.)

To all whom it may concern:

Be it known that I, FREDERICK F. Tons- BERG, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Valves, of which the following is a specification.

My invention relates to valves, particularly such as are used to admit and exhaust water or other fluid toand from a hydraulic elevator, compressor, press, or the like.-

It consists of simple means for opening and closing both valves by a single motion and of packing the valve against leakage.

It further consists of other novel features of construction, all as will be hereinafter fully set forth. I

Figures 1 and 2represent, respectively, vertical and horizontal sections of a device embodying my invention, a portion of Fig. 2 being in plan view.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, 1 designates the body or casing of avalve formed with lateral an accumulator (not shown) and having achamber 8 for a valve 9. This valve 9 rests against a seat 10, shown as at the end of the bore 11 of the body 1. Its spindle 12 extends into the bore 11 and may be formed with wings 13 to maintain its axial relation thereto. At the other end of the body 1 is another lug 14, adapted to form a pivot for a lever 15, the end of which is slotted at 16 for engagement with a pin 17 in a fork 18 at the end of a stem 19. This stem fits smoothly into the bore 11 of the body 1, is recessed at 20 for the reception of a packing 21, and reduced at 22 to enter a bushing 23, which fits loosely on the portion, 22 and is longitudinally split at 24. The portion 22 is longitudinally and laterally bored at 25 26, as shown'in Fig. 1. Screwed to the threaded end of the portion 22 is a tapered extension-piece 27, having a pin 28, formed with wings 29. A bore in the piece 27 connectswith-the bore 25 on the stem 19.

The operation is as follows: When the parts stand as shown in Fig. 1, the inlet-valve 9 is forced from its seat 10 by the contact of the stem 19 is retracted to the position shown in Fig. 2, the inlet-valve 9 is promptly closed by the water-pressure. Simultaneously the offset 3 is opened to the bore 11, so that the Water may exhaust from the cylinder therethrough. The packing 21 is sufficient to prevent leakage during this wasting of the water from the cylinder.

It is clear that by my construction the stem 19 and all its attached parts may be withdrawn for repairs or the like without loss of water or energy, the inlet-valve 9 remaining seated.

Various changes may be made in the details of construction shown without departing from the general spirit of my invention, and I do not, therefore, desire to be limited in each case to the same.

Having thus described my invention, whatl claim as new, and desire to secure by Letters Patent, is-- 1. A valve comprising a longitudinallybored body and a plurality of lateral passages, an inlet-valve closing one end of said bore and having a spindle projecting thereinto, a stem passing through the other end of said bore and longitudinally adjustable therein, manually-operated means outside of said body for reciprocating said stem, said stem fitting snugly in said bore and adapted to close one of said lateral passages and to contact-with the spindle of said inlet-valve whereby the closing of one of said lateral passages admits fluid from said inlet to the other lateral passage and the opening of said bore between said lateral passages permits the closing of said inlet-valve by the fluid-pressure.

2. A valve comprising a tubular body having an inlet-port adjacant one end and a plurality of lateral ports, an inlet-valve closable by fluid-pressure, a stem fitted snugly in the bore of said body and having a recess and a reduced portion beyond said recess having longitudinal and lateral bores, a packing in said recess, a bushing on said reduced portion and a tapered extension-piece on said reduced portion beyond the bushing and having a longitudinal bore communicating with the longitudinal bore of the said reduced portion of the stem.

3. A valve comprising a tubular body having an inlet-port adjacent one end and a plurality of lateral ports, an inlet-valve closable by fluid-pressure, a stem snugly fitted in the bore of said body and having a recess and a reduced portion, a packing in said recess, longitudinal and lateral passages in said stem, a bushing on said reduced portion, a tapered extension-piece on said reduced portion having a longitudinal bore communicating With the longitudinal bore of the stem, said extensionpiece having a pin provided with Wings with a passage through said pin.
